The new lava lake in Pu‘u ‘Ō‘ō has buried much of the floor of Aug 4

The new lava lake in Pu‘u ‘Ō‘ō has buried much of the floor of the August 3, 2011, collapse crater beneath a maximum of about 45 m (~148 ft) of lava. Most of the lava upwells at the east end of the lake (lower right) and flows toward the west, much like the lava lake prior to the August 3 flank breakout and crater collapse.
